future compression requests.
For decompression requests, the 842 hardware driver contains
a software implementation of the 842 decompressor to support
the decompression of data that was compressed before the accelerator
went offline.

When the nx driver was pulled, the Makefile that actually
builds it is arch/powerpc/Makefile. This is unnatural.
This patch moves the line that builds the nx driver from
arch/powerpc/Makefile to drivers/crypto/Makefile where it
belongs.

I am currently working on the zcache RAM compression driver (in the staging

I am looking to use the crypto compression API instead of the hardcoded LZO
